Abstract
Description
本發明大體上關於經塗覆的基材,且更明確言之,是關於欲進行雷射切割之經塗覆基材(coated substrate)的雷射製備方法。The present invention relates generally to coated substrates and, more specifically, to laser fabrication methods for coated substrates to be laser cut.
精密微加工技術的進步及相關製程的改進使得尺寸得以縮小、重量減輕且降低材料成本,而有助於諸如但不限於可用於觸控螢幕、平板電腦、智慧型手機及電視之平面顯示器等產品快速成長。由於這些進步,使得超快速工業雷射成為用在需要高精密微加工之應用上的重要工具。期望可使用這類雷射的雷射切割製程以可控制的方式來分割基材,所生成的碎屑可忽略不計且對基材造成最少缺陷及低的表面下(subsurface)損傷。在不限制本發明的情況下,藉由形成垂直斷裂線或受損印跡來建立阻力最小的裂紋擴大路徑以沿著該路徑分割基材,可使某些雷射切割製程符合此等期望。此等製程使破裂及分割作用侷限在該受損印跡處並防止在基材的任何其他部分中產生裂紋或使裂紋減至最少。Advances in precision micromachining technology and improvements in related processes have enabled size reduction, weight reduction, and material cost reduction, and are useful for products such as, but not limited to, flat panel displays for touch screens, tablets, smart phones, and televisions. growing up very fast. As a result of these advances, ultra-fast industrial lasers have become an important tool for applications requiring high precision micromachining. It is desirable to use a laser cutting process using such lasers to divide the substrate in a controlled manner, resulting in negligible debris and minimal defects and low subsurface damage to the substrate. Without limiting the invention, certain laser cutting processes may meet such expectations by forming a vertical fracture line or a damaged footprint to create a crack-extended path with minimal resistance to split the substrate along the path. These processes limit the rupture and segmentation to the damaged footprint and prevent cracking or minimize cracking in any other portion of the substrate.
基材表面上的塗層可能降低雷射切割製程的效果。例如,塗層可能吸收部分的雷射光束、改變雷射光束進入基材內部部分的傳播作用。這會進而限制雷射能量到達基材內部部分的量,而降低在基材中所形成之受損印跡的品質。因此,使裂紋擴大作用侷限在該受損印跡處這件事變得較不可預期且較不易控制,也使基材分割變得較為困難。此外,分割經塗覆的基材可能形成無法接受的碎屑量,且亦可能對該基材的該等分割部分造成缺陷或表面下的損傷。The coating on the surface of the substrate may reduce the effectiveness of the laser cutting process. For example, the coating may absorb a portion of the laser beam and change the propagation of the laser beam into the interior portion of the substrate. This in turn limits the amount of laser energy reaching the inner portion of the substrate, while reducing the quality of the damaged print formed in the substrate. Therefore, the limitation of crack propagation to the damaged footprint becomes less predictable and less controllable, which also makes substrate segmentation more difficult. In addition, segmenting the coated substrate may result in an unacceptable amount of debris and may also cause defects or subsurface damage to the segmented portions of the substrate.
根據本發明一實施例提供一種供欲接受雷射切割之經塗覆基材用的雷射製備方法。該方法包括引導雷射燒蝕光束至聚合物塗層的目標部分,以從經塗覆的基材上實質去除該目標部分,其中該聚合物塗層的該目標部分具有介於約10微米至約6.0毫米間的寬度。According to an embodiment of the invention, a laser preparation method for a coated substrate to be subjected to laser cutting is provided. The method includes directing a laser ablation beam to a target portion of a polymer coating to substantially remove the target portion from the coated substrate, wherein the target portion of the polymer coating has a thickness of between about 10 microns Width of about 6.0 mm.
根據本發明另一實施例提供一種用於雷射切割經塗覆基材的方法。該方法包括引導雷射燒蝕光束至聚合物塗層的複數個目標部分,以從經塗覆的基材上實質去除該複數個目標部分而形成預定塗層去除圖案。該方法進一步包括引導雷射切割光束沿該預定塗層去除圖案行進,及使該經塗覆的基材分割成至少兩個經塗覆部分。該預定塗層去除圖案具有介於約10微米至約6.0毫米間的寬度。In accordance with another embodiment of the present invention, a method for laser cutting a coated substrate is provided. The method includes directing a laser ablation beam to a plurality of target portions of a polymer coating to substantially remove the plurality of target portions from the coated substrate to form a predetermined coating removal pattern. The method further includes directing the laser cutting beam to travel along the predetermined coating removal pattern and dividing the coated substrate into at least two coated portions.

In particular, individual features may also be omitted or combined in some other manner with the same exemplary embodiment or with other features shown in other exemplary embodiments.
本發明實施例是關於可供欲接受雷射切割之經塗覆基材用的雷射製備方法及有關用來雷射切割經塗覆之基材的方法。如文中所述,經塗覆之基材塗有聚合物塗層。例如,聚合物塗層可包括但不限於高折射率聚合物(HRIP)、保護性聚合物膜及光阻劑材料。文中所使用的高折射率聚合物(HRIP)一詞是用來表示具有大於1.50之折射率的聚合物。又如文中所述般,基材為雷射燒蝕光束波長可穿透的材料,該材料可為,但不限於,玻璃、熔融矽石(fused silica)、藍寶石或雷射燒蝕光束波長可穿透的任何其他材料。Embodiments of the present invention relate to laser preparation methods for coated substrates that are subject to laser cutting and to methods for laser cutting coated substrates. As described herein, the coated substrate is coated with a polymeric coating. For example, the polymer coating can include, but is not limited to, a high refractive index polymer (HRIP), a protective polymer film, and a photoresist material. The term high refractive index polymer (HRIP) as used herein is used to mean a polymer having a refractive index greater than 1.50. As described herein, the substrate is a material that is transparent to the wavelength of the laser ablation beam, which may be, but is not limited to, glass, fused silica, sapphire, or laser ablation beam wavelengths. Any other material that penetrates.
根據本發明實施例,經塗覆之基材的雷射製備方法包括引導雷射燒蝕光束至聚合物塗層的目標部分,以實質去除該聚合物塗層的該目標部分。較佳者,實質去除聚合物塗層的目標部分包括去除該聚合物塗層之該目標部分處約100%的聚合物。然而,亦可設想實質去除聚合物塗層的目標部分可包括去除該聚合物塗層之該目標部分處超過約90%、或超過約95%或甚至高過約98%的聚合物。當用於本文中,「雷射燒蝕光束(ablative laser beam)」一詞為配置用來造成聚合物塗層材料燒蝕的雷射光束。可由皮秒雷射或飛秒雷射發射該雷射燒蝕光束,其中該等雷射可為脈衝式雷射且可配置用來產生單次雷射脈衝或脈衝叢發,藉以形成雷射燒蝕光束而與該經塗覆基材的聚合物塗層產生交互作用。該雷射燒蝕光束可具有會被聚合物塗層所吸收的波長。藉著聚合物塗層吸收該雷射光束,該雷射光束不會進入下方基材中且不會加熱該下方基材或在該下方基材中造成應力。或者,該雷射燒蝕光束在該目標部分處所具有的強度可在該雷射燒蝕光束之焦點體積(focal volume)內的聚合物塗層中產生多光子吸收作用。該雷射燒蝕光束的波長及/或強度可根據該經塗覆基材的聚合物塗層材料而改變。此外,該雷射的脈衝持續時間(pulse duration)可加以選擇,使得在交互作用時間內沒有顯著的熱從該目標部分擴散出來(特別是例如:τ<<d2 /α,其中d為雷射光束的焦點直徑,τ為雷射脈衝持續時間,及α為聚合物材料的熱擴散常數)。In accordance with an embodiment of the present invention, a laser preparation method for a coated substrate includes directing a laser ablation beam to a target portion of a polymer coating to substantially remove the target portion of the polymer coating. Preferably, substantially removing the target portion of the polymeric coating comprises removing about 100% of the polymer at the target portion of the polymeric coating. However, it is also contemplated that substantially removing the target portion of the polymeric coating can include removing more than about 90%, or more than about 95% or even more than about 98% of the polymer at the target portion of the polymeric coating. As used herein, the term "ablative laser beam" is a laser beam configured to cause ablation of a polymeric coating material. The laser ablation beam can be emitted by a picosecond laser or a femtosecond laser, wherein the laser can be a pulsed laser and can be configured to generate a single laser pulse or pulse burst to form a laser burn The beam is etched to interact with the polymer coating of the coated substrate. The laser ablation beam can have a wavelength that is absorbed by the polymer coating. The laser beam is absorbed by the polymer coating, the laser beam does not enter the underlying substrate and does not heat the underlying substrate or cause stress in the underlying substrate. Alternatively, the intensity of the laser ablation beam at the target portion can produce multiphoton absorption in the polymer coating within the focal volume of the laser ablation beam. The wavelength and/or intensity of the laser ablation beam can vary depending on the polymeric coating material of the coated substrate. Furthermore, the pulse duration of the laser can be selected such that no significant heat is diffused from the target portion during the interaction time (especially for example: τ<<d 2 /α, where d is Ray The focal diameter of the beam, τ is the duration of the laser pulse, and α is the thermal diffusion constant of the polymer material).
引導雷射燒蝕光束至目標部分可包括對該聚合物塗層的該目標部分施加至少一雷射脈衝。在該聚合物塗層的該目標部分處進行燒蝕(ablation)之後,該雷射燒蝕光束可對準該聚合物塗層的後續目標部分,而得以對該聚合物塗層的該後續目標部分施加後續雷射脈衝以實質去除該經塗覆基材上的該後續目標部分。在該聚合物塗層的該後續目標部分處進行燒蝕之後,該雷射燒蝕光束可視需要進行任意次數的重新對準以對該聚合物塗層的多個後續目標部分施加後續雷射脈衝並根據預定的塗層去除圖案來持續進行此動作。由於該雷射燒蝕光束可聚焦成具有直徑及周長的圓點,故可藉著使該雷射燒蝕光束的焦點有至少一部分與該先前已去除之目標部分的至少一部分重疊的方式依據預定塗層去除圖案來去除目標部分。以此方式,該預定塗層去除圖案可為具有實質一致寬度的實質直線。如以下所述,該預定塗層去除圖案的寬度可實質等於該雷射燒蝕光束之焦點的直徑。在任何情況下,該預定塗層去除圖案的寬度實質等於該目標部分的寬度,該目標部分的寬度可例如為約10微米至約6.0毫米,例如約100微米至約4.0毫米或甚至約200微米至約2.0毫米。可對該等目標部分的每個部分施加任意次數的雷射脈衝以求實質去除該聚合物塗層的該目標部分。在某些情況下,每個目標部分接受一次雷射脈衝可能足以實質去除該聚合物塗層的每個目標部分。或者,可對該等目標部分各自施加兩次或更多次雷射脈衝以去除該聚合物塗層的該等目標部分。Directing the laser ablation beam to the target portion can include applying at least one laser pulse to the target portion of the polymer coating. After ablation at the target portion of the polymer coating, the laser ablation beam can be aligned to a subsequent target portion of the polymer coating to achieve the subsequent target of the polymer coating. A subsequent laser pulse is applied in part to substantially remove the subsequent target portion on the coated substrate. After ablation at the subsequent target portion of the polymer coating, the laser ablation beam can be realigned as many times as needed to apply subsequent laser pulses to a plurality of subsequent target portions of the polymer coating. This action is continued in accordance with a predetermined coating removal pattern. Since the laser ablation beam can be focused into a circle having a diameter and a perimeter, the manner in which at least a portion of the focus of the laser ablation beam overlaps at least a portion of the previously removed target portion can be relied upon. The coating is removed from the pattern to remove the target portion. In this manner, the predetermined coating removal pattern can be a substantially straight line having a substantially uniform width. As described below, the predetermined coating removal pattern may have a width substantially equal to the diameter of the focus of the laser ablation beam. In any event, the predetermined coating removal pattern has a width substantially equal to the width of the target portion, and the target portion may have a width of, for example, from about 10 microns to about 6.0 mm, such as from about 100 microns to about 4.0 mm or even about 200 microns. Up to about 2.0 mm. Any number of laser pulses can be applied to each portion of the target portions to substantially remove the target portion of the polymer coating. In some cases, receiving a laser pulse for each target portion may be sufficient to substantially remove each target portion of the polymer coating. Alternatively, two or more laser pulses may be applied to each of the target portions to remove the target portions of the polymer coating.
引導雷射燒蝕光束至目標部分可包括在該經塗覆基材的經塗覆表面附近配置該雷射燒蝕光束來源及對該聚合物塗層的該目標部分施加至少一雷射脈衝。或者,當該經塗覆基材包括至少一未經塗覆的表面時,引導雷射燒蝕光束至目標部分的步驟可包括在該至少一未經塗覆的表面附近配置該雷射燒蝕光束來源,及引導該雷射燒蝕光束前往該至少一未經塗覆的表面並通過該基材而到達該聚合物塗層,以對該聚合物塗層的該目標部分施加至少一雷射脈衝。Directing the laser ablation beam to the target portion can include disposing the source of the laser ablation beam adjacent the coated surface of the coated substrate and applying at least one laser pulse to the target portion of the polymer coating. Alternatively, when the coated substrate comprises at least one uncoated surface, the step of directing the laser ablation beam to the target portion can include disposing the laser ablation near the at least one uncoated surface Source of the beam, and directing the laser ablation beam to the at least one uncoated surface and through the substrate to reach the polymer coating to apply at least one laser to the target portion of the polymer coating pulse.

As used herein, a relatively small focus is a laser beam spot having a diameter that is less than the width of the target portion of the polymer coating. Such relatively small focus cannot form the predetermined coating removal pattern by moving the laser ablation beam alone (or moving the coated substrate) in the x-direction or the y-direction. Using such a relatively small focus laser pulse, the laser ablation beam can also be directed at an additional location of the target portion to scan to remove the target portion.
通常,會對欲接受雷射切割的經塗覆基材進行製備,以期僅沿預定塗層去除圖案來去除聚合物塗層的目標部分而不會去除該經塗覆基材之該聚合物塗層的其他部分。當已去除該聚合物塗層的該等目標部分之後,引導雷射切割光束沿著該預定塗層去除圖案行進,該雷射切割光束將不會接觸到該經塗覆基材之該聚合物塗層的其他部分。此方式可進而使該聚合物塗層之其他部分的去除或劣化情況減至最少,同時亦可防止該聚合物塗層在該雷射切割光束傳播方面上可能有所變化作用的情況發生。根據本發明實施例,該等目標部分具有足以容納雷射切割光束的寬度。Typically, a coated substrate to be subjected to laser cutting is prepared in order to remove the target portion of the polymer coating only by removing the pattern along the predetermined coating without removing the polymer coating of the coated substrate.

As shown, in step 102, the laser ablation beam is directed to a target portion of the polymer coating to substantially remove the target portion of the polymer coating from the coated substrate. At step 104, at least one laser pulse is applied to the target portion of the polymer coating. At step 106, the laser ablation beam is directed at a subsequent target portion of the polymer coating. At step 108, at least one subsequent laser pulse is applied to the subsequent target portion of the polymer coating. At step 110, it is determined whether the predetermined coating removal pattern is completed. If not, the method returns to step 106 to align the laser ablation beam with a subsequent target portion of the polymer coating. If it is judged that the coating removal pattern has been completed, the method can be ended.
本發明實施例亦有關用來雷射切割經塗覆基材的方法。在該經塗覆基材的製備製程中,藉著引導雷射燒蝕光束至該聚合物塗層的複數個目標部分而沿著預定塗層去除圖案實質去除該聚合物塗層的該複數個目標部分,接著是,在已去除該聚合物塗層的該等目標部分之後可引導雷射切割光束沿著該預定塗層去除圖案行進,以將該經塗覆基材分割成多個經塗覆的部分。如上所述,本發明實施例有助於引導雷射切割光束順著該預定塗層去除圖案行進,其中該雷射切割光束不會與該經塗覆基材之該聚合物塗層的其他部分接觸。Embodiments of the invention are also directed to methods for laser cutting a coated substrate. In the preparation process of the coated substrate, the plurality of polymer coatings are substantially removed along the predetermined coating removal pattern by directing the laser ablation beam to the plurality of target portions of the polymer coating. a target portion, followed by guiding the laser cut beam along the predetermined coating removal pattern after the target portions of the polymer coating have been removed to divide the coated substrate into a plurality of coated Covered part. As described above, embodiments of the present invention facilitate directing a laser cutting beam to travel along the predetermined coating removal pattern, wherein the laser cutting beam does not interact with other portions of the polymer coating of the coated substrate. contact.
引導雷射切割光束沿著該預定塗層去除圖案行進的步驟包括使脈衝式雷射切割光束在該經塗覆基材中聚焦成雷射光束聚焦線,以沿著該經塗覆基材中的該雷射切割光束聚焦線產生誘發性吸收作用(induced absorption)。該脈衝式雷射切割光束聚焦在該經塗覆基材中的複數個位置處而沿著該經塗覆基材中的該雷射切割光束聚焦線產生誘發性吸收作用,並在該經塗覆基材中之該複數個位置的每個位置處沿著該雷射切割光束聚焦線形成受損印跡(damage track)。就每個雷射脈衝而言,會沿著該雷射切割光束聚焦線在該經塗覆基材中製造出個別的受損印跡。在該經塗覆基材中之該複數個位置的每個位置處所形成一連串的此等受損印跡可能彼此之間靠得夠近而沿著該預定塗層去除圖案挨在一起以形成橫向連接的該等受損印跡,並可沿著該等受損印跡使該經塗覆基材分割開來。為此,該雷射以特定重複速率進行脈衝。雷射點的尺寸及間距可加以選擇,如此得以沿著該等雷射點的線在該表面處形成期望的受損印跡。The step of directing the laser cutting beam to travel along the predetermined coating removal pattern includes focusing a pulsed laser cutting beam in the coated substrate into a laser beam focusing line to be along the coated substrate The laser cutting beam focus line produces induced absorption. The pulsed laser-cut beam is focused at a plurality of locations in the coated substrate to induce absorption along the laser-cut beam focus line in the coated substrate, and the coating is applied A damage track is formed along the laser cut beam focus line at each of the plurality of locations in the substrate. For each laser pulse, an individual damaged footprint is created in the coated substrate along the laser cutting beam focus line. A series of such damaged prints formed at each of the plurality of locations in the coated substrate may be close enough to each other and joined together along the predetermined coating removal pattern to form a lateral connection The damaged imprints can be separated along the damaged imprints. To this end, the laser is pulsed at a specific repetition rate. The size and spacing of the laser spots can be selected such that a desired damaged footprint is formed at the surface along the lines of the laser points.
本發明實施例可進一步包括使該經塗覆基材分割成至少兩個經塗覆的部分。較佳沿著橫向連接的該等受損印跡來分割該經塗覆基材。分割(separating)該經塗覆基材的步驟可包括對該經塗覆基材施加熱應力。該熱應力可例如為不均勻地加熱或冷卻該經塗覆基材。可使用CO2 雷射沿著該等橫向連接的受損印跡照射該經塗覆基材來施加該等熱應力。或者,分割該經塗覆基材的步驟可包括對該經塗覆基材施加機械性應力。施加此等應力具有促使裂紋沿著該等個別受損印跡及沿著該等橫向連接的受損印跡而擴大的效果,使得該基材可分割成多個經塗覆的部分。Embodiments of the invention may further include dividing the coated substrate into at least two coated portions. Preferably, the coated substrate is divided along the damaged prints that are laterally joined. The step of separating the coated substrate can include applying thermal stress to the coated substrate. The thermal stress can be, for example, uneven heating or cooling of the coated substrate. The coated substrate can be illuminated with the CO 2 laser along the laterally connected damaged blots to apply the thermal stresses. Alternatively, the step of dividing the coated substrate can include applying a mechanical stress to the coated substrate. Applying such stress has the effect of causing the crack to expand along the individual damaged prints and along the transversely attached damaged prints such that the substrate can be divided into a plurality of coated portions.
根據本發明實施例,該雷射切割光束的波長實質上可穿透該基材的材料。實質上可穿透一詞,意指該雷射切割光束的強度於該光束方向上在基材中每毫米之穿透深度的光束強度衰減量為約15%或更少。該雷射可例如波長為1064奈米的Nd:YAG雷射或波長為1030奈米的Yb:YAG雷射,或特別是對於紅外線波長範圍可透射的半導體基材而言,該雷射可為波長範圍介於約1.5微米至約1.8微米間的Er:YAG雷射。According to an embodiment of the invention, the wavelength of the laser cut beam is substantially transparent to the material of the substrate. The term "substantially permeable" means that the intensity of the intensity of the laser-cut beam in the direction of the beam in the direction of penetration of the beam per millimeter of penetration in the substrate is about 15% or less. The laser can be, for example, a Nd:YAG laser having a wavelength of 1064 nm or a Yb:YAG laser having a wavelength of 1030 nm, or particularly for a semiconductor substrate that is transmissive in the infrared wavelength range, the laser can be An Er:YAG laser having a wavelength ranging from about 1.5 microns to about 1.8 microns.
該雷射切割光束的脈衝持續時間可加以選擇,使得在交互作用的時間內沒有顯著的熱從該交互作用區域擴散出來(特別是例如:τ<<d2 /α,其中d為焦點直徑,τ為雷射脈衝持續時間,及α為基材材料的熱擴散常數)。該雷射切割光束的脈衝能量可加以選擇,使得該交互作用區域內的強度(即為在該聚焦線中的強度)能產生誘發性吸收作用。該聚焦線可具有介於約0.1毫米至約100毫米間的長度。The pulse duration of the laser-cut beam can be selected such that no significant heat is diffused from the interaction region during the interaction time (especially for example: τ<<d 2 /α, where d is the focal diameter, τ is the duration of the laser pulse, and α is the thermal diffusion constant of the substrate material). The pulse energy of the laser-cut beam can be selected such that the intensity within the interaction region (i.e., the intensity in the focus line) produces an induced absorption. The focus line can have a length of between about 0.1 mm to about 100 mm.
該雷射切割光束的偏極性(polarization)可能影響在表面處的交互作用(反射率)及在發生該誘發式吸收作用處之材料內的交互作用類型。可藉由在熱激發之後誘發出自由電荷載子(通常是電子)的方式、或藉由多光子吸收作用及內部光致離子化作用(internal photoionization)的方式、或藉由進行直接場致離子化作用(光的場強度直接打斷電子鍵結)而發生該誘發式吸收作用。可例如使用所謂的凱迪希參數(Keldysh parameter)來判斷所生成的電荷載子類型。對於某些材料而言(例如,雙折射性材料),該雷射光的進一步吸收/透射作用取決於偏極性而定這點可能是重要的,且因此該使用者可(例如藉由簡單地探試方式)選擇使用合適的透鏡進行偏極化以利於分割各別的材料。因此,若該材料不是光等向性(optically isotropic),而例如是雙折射性時,該雷射光在材料中的傳播亦會受到偏極性的影響。因此,偏極性及偏極向量(polarization vector)的方向可加以選擇,而得以如期望般地僅形成一條聚焦線,而不是兩條(尋常射線及異常射線)。The polarization of the laser-cut beam may affect the interaction at the surface (reflectance) and the type of interaction within the material where the induced absorption occurs. Can be induced by free charge carriers (usually electrons) after thermal excitation, or by multiphoton absorption and internal photoionization, or by direct field ionization This induced absorption occurs when the action (the field strength of the light directly interrupts the electron bond). The so-called Keldysh parameter can be used, for example, to determine the type of charge sub-generated. For certain materials (eg, birefringent materials), it may be important that the further absorption/transmission of the laser light depends on the polarity, and thus the user may (for example by simply exploring Trial mode) Select to use a suitable lens for polarization to facilitate segmentation of individual materials. Therefore, if the material is not optically isotropic, and is, for example, birefringent, the propagation of the laser light in the material is also affected by the polarity. Therefore, the direction of the polarity and the polarization vector can be selected to form only one focus line as desired, instead of two (normal rays and abnormal rays).
再者,可依據脈衝持續時間、脈衝能量及聚焦線的直徑來選擇強度,使得較佳是在該基材的微結構中,不會發生大量燒蝕或大量熔化的情形,而是較佳僅會形成受損印跡。對於諸如玻璃或透明晶體這類典型的材料而言,使用次奈秒(sub-nanosecond)範圍內(即,特別是使用例如介於約0.1皮秒(ps)至約100ps間且較佳少於約15ps之脈衝持續時間)的脈衝雷射可最容易滿足此項要求。Furthermore, the intensity can be selected according to the pulse duration, the pulse energy and the diameter of the focus line, so that it is preferred that in the microstructure of the substrate, a large amount of ablation or a large amount of melting does not occur, but preferably only A damaged blot will be formed. For typical materials such as glass or transparent crystals, use in the sub-nanosecond range (i.e., especially using, for example, between about 0.1 picoseconds (ps) to about 100 ps and preferably less than A pulsed laser with a pulse duration of about 15 ps is the easiest to meet this requirement.
在某些實施例中,該雷射切割光束聚焦線的平均直徑δ(即,焦點直徑)介於約0.3微米至約5.0微米間,較佳介於約1.0微米至約3.0微米間,更佳介於約0.4微米至約4.0微米間,且甚至更佳為約2.0微米,及/或該雷射切割光束的脈衝持續時間τ可加以選擇,而使得在該雷切割光束與該基材材料交互作用的時間內,該材料中的熱擴散作用可忽略不計,較佳不會發生熱擴散作用,為此較佳是根據τ<<d2 /α來設定τ、δ及該基材材料的熱擴散常數α,及/或較佳τ可選定為少於約10奈秒(ns)、更佳為少約100皮秒(ps),及/或該雷射切割光束的脈衝重複率介於約10kHz至約1000kHz間(例如,約100kHz),及/或該雷射切割光束可採用單次脈衝式雷射或叢發脈衝式(burst-pulse)雷射般的操作方式,且每次叢發脈衝的能量介於約40微焦耳(uJ)至約1000uJ,及/或在該雷射切割光束之切割端所直接測得的平均雷射功率為介於約10瓦(watts)至約100瓦間,例如介於約30瓦至約50瓦間。In some embodiments, the laser cutting beam focus line has an average diameter δ (ie, a focal diameter) of between about 0.3 microns and about 5.0 microns, preferably between about 1.0 microns and about 3.0 microns, more preferably between Between about 0.4 microns and about 4.0 microns, and even more preferably about 2.0 microns, and/or the pulse duration τ of the laser-cut beam can be selected such that the Ray-cut beam interacts with the substrate material During the time, the thermal diffusion in the material is negligible, and preferably no thermal diffusion occurs. For this reason, it is preferred to set τ, δ and the thermal diffusion constant of the substrate material according to τ<<d 2 /α. α, and/or preferably τ may be selected to be less than about 10 nanoseconds (ns), more preferably less than about 100 picoseconds (ps), and/or the laser cutting beam has a pulse repetition rate of between about 10 kHz and Between approximately 1000 kHz (eg, approximately 100 kHz), and/or the laser-cut beam may be operated in a single pulsed or burst-pulse-like manner, and each burst pulsed The energy is between about 40 microjoules (uJ) to about 1000 uJ, and/or directly measured at the cut end of the laser cutting beam The average laser power between about 10 W (Watts) to between about 100 Watts, such as between about 30 watts to about 50 watts room.
